Other forms: suns
The sun is the burning ball in the sky that gives daylight and warmth. In the sun, the sun came out, sun cream.
It is a star, about a hundred and nine times the diameter of the earth, and its light takes roughly eight minutes to arrive. Sunrise, sunset, sunburn, sunflower and sunshine are standard compounds. Note under the sun, meaning anywhere at all; make hay while the sun shines; a place in the sun; and that the sun is capitalised as Sun when named as one star among others.

Old English sunne descends from a Proto-Indo-European root that also gives Latin sol and Greek helios. Sunday is the sun's day, translated from Latin, which took it from Greek and Babylonian astronomy.
